Inventor: BUTLER HENRY JAMES
IPC: F16D55/228
Filed: 1960-03-05
Abstract: 971,371. Disc brakes. DUNLOP RUBBER CO. Ltd. Feb. 22, 1961 [March 5, 1960], No. 7883/60. Heading F2E. In a disc brake, piston housing on each side of the disc are movable parallel to the plane of the disc, against springs, under brake reaction to displace liquid for servo application of the same, or another, brake. A slotted base-plate 11 fixed to the vehicle embraces chordwise a disc 10 attached to a vehicle front wheel, and carries end blocks 28 in which slide end spigots 16, 17 of brake piston housings 14. The housings 14 are joined by a bracing member 15 and form cylinders for brake pistons 24 bearing on friction pads 25. The spigots 16 are engaged by spring-loaded plungers 20 which tend to resist movement of the housings under braking torque. The plungers 20 are carried in servocylinders 19 filled with liquid such that movement of the housings 14 under braking torque displaces liquid through outlet 27 for the servo operation of the rear brakes. In a modification, cup-shaped pistons are used, the applying liquid pressure acting on the annular rim and the servo pressure from the cylinders 19 acting on the central area of the piston to render the brake self-sensing.

Title: Thermoscope apparatus
IPC: G01J5/28
Filed: 1968-02-19
Abstract: 1,219,203. Infra-red viewing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Feb., 1968 [20 Feb., 1967], No. 7986/68. Heading H4F. The Specification describes a device for converting an infra-red image into a visible image and also for determining the temperature of the object providing the image. In Fig. 1 which is a plan view, a mirror 3 oscillates about a vertical axis and scans the object (below and to rightout of Figure) through an angle of 0À15 rad at 15 c/s. and directs the scanned light on to a vertical array of 40 infra-red sensitive photodetectors 1 subtending a vertical angle of 0À1 rad. via forming means 2. The image is thus analysed in 40 x 40 x (0À15/0 10) = 2,400 elementary areas. The infra-red radiation falling on the detectors is chopped at 2000 times per second by toothed disc 4. The disc is mounted in a thermally isolated housing 8 and has its surface covered with a material emitting black radiation of the temperature of the housing 8. The radiation falling on the detectors is thus alternately at levels determined by the object temperature and by the housing temperature. With the obejct temperature To below that of the housing temperature Te, the output of the detectors varies as shown in Fig. 2 (solid line). To make To equal to Te radiation can be added to or subtracted from the object radiation by source 11 and semi-permeable mirror 10 or attenuator 9, respectively. The amount of radiation biasing thus needed gives an indication of the object temperature. To produce the visible image of the object, each detector is connected to a respective electro-luminescent diode in a vertical array 5, which are viewed via the reverse side of mirror 3.

Abstract: 587,677. Aerials. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1944, No. 8595. Convention date, Oct. 7, 1942. [Class 40 (v)] A wide-band loop antenna arrangement comprises a number of radiating elements of one half wavelength or less at the operating frequencies arranged in a substantially closed planar pattern, the elements being energized at their ends and supported by a single conductive mast extending within and normal to the planar pattern, and conductive supporting means for each of the elements fastened at one end to the mast and at the other end to the inner surface of the corresponding element. As shown, the radiating elements 1 ... 4 are supported by conductive rods 14 ... 17 secured to a sleeve 18 mounted on a shield 5 through which the transmission lines 6, 7 pass. Branch conductors 8, 9, 10, 11 are connected to diagonally opposite points of the square arrangement so that the current flow is in the same direction around the periphery of the closed pattern.

The length. of the elements is approximately one half to one-tenth of the wavelength of -the operating frequency. The construction eliminates voltage surges at the centre of the antenna array and the employment of conductive supports provides an inherent protection against lightning. In a modified arrangement, Fig. 3 (not shown), two closed patterns of radiating elements arranged vertically on a mast, and preferably spaced one-half wavelength apart, may be energized in phase or in other phase relation by appropriate arrangement and length of the conductors between corresponding connecting points of the two patterns.
